Detects LockerGoga ransomware activity via specific command line.
Detects WannaCry ransomware activity
Detects a specific command used by the Conti ransomware group
Detects LockerGoga ransomware activity via specific command line.
Detects the execution of a renamed "gpg.exe". Often used by ransomware and loaders to decrypt/encrypt data.
Detects the execution of "gpg.exe" from uncommon location. Often used by ransomware and loaders to decrypt/encrypt data.
Detects the load of RstrtMgr DLL (Restart Manager) by an uncommon process.
This library has been used during ransomware campaigns to kill processes that would prevent file encryption by locking them (e.g. Conti ransomware, Cactus ransomware). It has also recently been seen used by the BiBi wiper for Windows.
It could also be used for anti-analysis purposes by shut downing specific processes.

'This query looks for file hashes and AV signatures associated with Prestige ransomware payload.'
'Dev-0530 actors are known to encrypt the contents of the victims device as well as renaming the file extensions. This query looks for the creation of files with .h0lyenc extension or presence of ransom note.'
This query was originally published in the threat analytics report, Cypherpunk ransomware leaves wake of tampered AVs.
Cypherpunk is a human-operated ransomware campaign named after the unusual .cypherpunk extension given to encrypted files. The attackers often used PSEXESVC, a service that helps the PsExe.exe utility run commands on a remote device. Both PSEXESVC and PsExe.exe are legitimate parts of Windows; however, they can be repurposed by attackers to perform malicious actions.
The query below can find instances of PSEXESVC being used to launch batch files, as often occurred in Cypherpunk attacks.

Use this query to look for running DarkSide ransomware behavior in the environment
This query was originally published in the threat analytics report, EvilQuest signals the rise of Mac ransomware.
As of the time of this writing (October 2020), ransomware designed to target macOS is relatively rare. EvilQuest is one of the few examples of this kind of malware on the platform.
The query below can detect the creation of a ransom note according to the typical methods of EvilQuest operators. The command the query searches for is associated with, but not definitely indicative of, EvilQuest infections.
Other queries related to EvilQuest ransomware can be found under the See also section below.

This query checks for attempts to stop at least 10 separate processes using the taskkill.exe utility. Run query
List alerts flagging attempts to delete backup files.
Looks for potential instances of bitlocker modifying registry settings to allow encryption, where it's executed via a .bat file.
This query checks for attempts to delete data on multiple drives using cipher.exe. This activity is typically done by ransomware to prevent recovery of data after encryption.
Total Controlled Folder Access events.
This query was originally published in the threat analytics report, RDP ransomware persists as Wadhrama.
The ransomware known as Wadhrama has been used in human-operated attacks that follow a particular pattern. The attackers often use Remote Desktop Protocol (RDP) to gain initial access to a device or network, exfiltrate credentials, and maintain persistance.
The following query checks for possible Wadhrama-related activity, by detecting the technique these attackers have used in the past to dump credentials.
Other techniques used by the group associated with Wadhrama are listed under See also.

The ransomware known as Wadhrama has been used in human-operated attacks that follow a particular pattern. The attackers often use Remote Desktop Protocol (RDP) to gain initial access to a device or network, exfiltrate credentials, and maintain persistance.
The following query checks for possible Wadhrama-related activity, by detecting any use of Windows Management Instrumentation command-line utility, or WMIC, to delete local backups. The attackers often delete all local backups on an infected device before actually running the ransomware.
